There are companies out there that specialize in that sort of thing.
Especially now that a lot of firms switch from microfiche to computers and
still want to have their old microfiches available for viewing on the
computer.  I found a company that does conversions in Germany.  But they
couldn't give me a quote without seeing a sample of the microfiche.  I have
not found a company that does this in the US.

Cheers,

Dear Gang,

I have estimated that one would need a scanner capable of an OPTICAL
resolution of 4000x4000 samples per inch in order to render the data in a
VW microfiche (interpolated resolution need not apply). No ordinary flatbed
can do that!!! Only a few high-end scanners are capable of this.

MJS
